GWT3500 ke transmitter e tobileng ea 1550nm DFB transmitter bakeng sa analog TV, digital TV le CMTS lipontšo tsa kabo ea fiber ea lehae le phetisetso ea fiber ea QAM TV Signal hole.Transmitter e sebelisa linearity e phahameng ea DFB laser, RF power digital process process, hammoho le RF pre-distortion circuit e ntlafalitsoeng ke Greatway Technology.Microprocessor e hahelletsoeng e lekola boemo ba ho sebetsa ba transmitter mme ka bo eona e netefatsa ts'ebetso e nang le tšepo.GWT3500 e loketse kabo ea faeba ea analoge ka har'a 20Km le QAM TV e tsamaisang sebaka se selelele ka har'a 100Km.

Fiber e ile ea hlahisoa ho fetisetsa CATV RF ka bo-1990 ka lebaka la ho fokotseha ha eona le bandwidth e batlang e se na moeli.RF to fiber converter ke sesebelisoa sa bohlokoa ka ho fetisisa.Ka amplifier ea lerata e tlase le microprocessor, kakaretso ea matla a RF ho laser e ka hlophisoa ka nepo, ea netefatsa index ea optical modulation index (OMI) e ntle ka ho fetisisa.Laser e pholileng ea DFB ho transmitter e tiisa hore DWDM optical wavelength e tsitsitse bakeng sa ho phatlalatsa kapa ho kenya litšebeletso tse kopanetsoeng tsa narrowcasting.Ho sa le joalo, laser ea DFB e pholileng e na le laser RIN e betere (lerata le matla) le matla a tsitsitseng a tsoang ka laser.Ortel-Emcore high linearity e pholisitsoeng laser ea DFB le moralo oa Greatway li pakiloe e le motsoako o atlehileng.GWT3500 optical transmitter e sebelisitsoe haholo ke bareki ba Amerika Leboea, Amerika Boroa le China ka ts'ebetso e ntle haholo le ts'epo e netefalitsoeng hantle.

Hammoho le Greatway high power optical amplifier, GWT3500 transmitter e ka fana ka fiber ea boleng bo holimo ea matšoao a TV mohahong kapa fiber lapeng.
